hey all i recently got myslef a cyma vsr for a SMLE project but im having a bit of trouble with it. so heres the situation, i load in a full mag, pull back the bolt and then all the bbs feed into the gun. so then i have to take out the mag, get all the bbs out and stick the mag back in, then it will either do the same with what ever bbs are left or ill be able to shoot the two or three left in the mag. is there anyway i can fix this?
